Asked if its growing operation in Dublin gave the firm options should they need to move business from London after the terms of Britain’s divorce from the European Union are known, a senior executive at the firm, Paul Hamill, said: “Dublin is an obvious hedge to a situation where you may be looking for another location for certain businesses.”

Citadel Securities executives told the Irish Times this week that the firm plans to treble its Irish workforce to 50 people within two years but that its decision to establish a base in Dublin predates Brexit.

Citadel Securities only operates in Dublin and London in the European Union. Hamill said the firm currently has no plans to open another office in the EU.
